OIL BURNER.

Application filed March 27, 1923.. Serial No. 628,032.

particularly to a. burner in which steam is employed with sufiicient pressure to act as an injector for the commingled steam and oil which is forced through the nozzle with sufficient pressure to vaporize the oil and spread it in order that it will create a flaring flame within a retort.

it is an objectof this invention to produce a burner of the character indicated which is practically noiseless as compared with steam-oil burners now in common use.

it is a further object of this invention to produce a burner of the character indicated which can be applied to furnaces now in common use without changing the construction of the furnace at all except as tothe door of the furnace which must be provided with apertures to receive the mountings by which the burner is installed and retained in place.

Furthermore, it is an object of the invention to produce a burner of the character indicated which can be moved with the door of the furnace when necessary and in which the supply of steam or oil may be changed to suit particular requirements as to the intensity of the flame, condition of the oil, etc.

It is a further object of this invention to provide a burner of the character indicated which will maintain an intensely hot flame without causing the temperature of the fire room to be unduly raised and in which the combustion of the fuel takes place almost instantaneously after it starts to ignite, a condition which insures the greatest amount of heat within the retort or furnace and which also prevents the loss. of energy as is the case where the combustion continues while the charge is passing from the furnace to the smoke uptake.

It has been found in practice that the device embodying the invention is highly efficient as. compared with burners now in common use and can be operated with a comparatively small consumption of fuel.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

in describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like characters denote corre sponding parts in the several views and in which Figure 1 illustrates a view in elevation of a burner, partly in section, applied to the door of a furnace;

Figure 2 illustrates a view in elevation of a fragment of the installation exteriorly of the furnace with part of the interior of the furnace also shown in elevation;

Figure 3 illustrates an enlarged sectional View of the furnace;

Figure 4 illustrates a sectional view on'a line corresponding with the line 44 of Figure 3; and

Figure 5 illustrates a view in elevation of th ct.

In these drawings 10 denotes the furnace, a fragment of which is conventionally shown, but as the particular type of furnace does not enter into the invention, it will not be described in detail.

The furnace door 11 may be of any ordinary type having a damper 12 and the door is employed as a support for the burner, as will presently appear.

A relatively large tube 13, which might be termed the burner casing, extends through an aperture 14 in the door and the outer end of the tube projects beyond the outer surface of the door. Rods 15 and 16 project through apertures in the door and their inner ends are connected to a hood 17 which hood has slots 17 and is also provided with an aperture 18 to receive the tube 13 so that the hood is mounted on or supported by the tube 18 and the rods 15 and 16. The outer ends of the rods terminate in handles which may be used to adjust the position of the hood 17, that is to say, the said hood may be forced inwardly or drawn outwardly to change the position of the hood with relation to the burner.

The tube also slides through a boss 19 which is secured to the outer face of the door and the tube is held in different positions of adjustment by a set screw 20 threaded in the said boss.

A steam pipe 21 and an oil supply pipe 22 are threaded in a head 23 provided with bores of different diameters. The bore of smaller diameter is in communication with the pipe 22 and the bore of larger diameter is in communication with the steam pipe 21. A tube 24 is threaded in the end of the head and is of the diameter of the larger bore of the head and the tube 24 is intended to receive the commingled steam and oil which is delivered to the interior of the furnace through the nozzle 25 which is threaded on the tube 24. The discharge orifices 26 of the nozzle are so formed as to produce a whirling motion to the commingled steam and oil as it escapes into the combustion chamber and this results in so distributing the vaporized fuel as to increase the area of V the flames produced by its combustion.

An apertured tube 27 has its end threaded in that portion of the head having the smaller bore and it communicates with the oil supply pipe 22. The inner end of the tube 27 is closed preferably by a plug 28 and therefore the oil is forced to escape from the tube through the apertures into the tube 24 and the steam travels to the inner end of the tube 24. Provision is made for controlling the pipes 21 and 22 through means of the valves 29 and 30 respectively so that elements have been described, it is believed that the operation will be understood by those skilled in the art without a detailed description thereof.

We claim- 'In a burner, a tube mounted to communicate with the interior of'a furnace and slidably held in place, a hood on the inner end of the tube, said hood having an inwardly flared wall, a handle secured to the said hood and extending through the door whereby motion is imparted to the hood for sliding the tube in the door, the said hood having a peripheral slot, a tube extending through the first mentioned tube in spaced relation thereto whereby a channel is formed between the two tubes, a jet on the inner end of the'second mentioned tube with relation to which the hood is movable for increasing or diminishing the space between the hood and the jet, an apertured tube within the second mentioned tube maintained in spaced relation thereto for forming a passage between the two tubes, a header to which the second and third mentioned tubes are connected, andpipes in communication with the third mentioned ,tubeand with the space between the second and third mentioned tubes respectively, for supplying fuel and airto be commingled and forced to the jet, substantially as described.
